Support vs Combat Heroes
There is no single right answer — the best mastery tree depends on whether you are racing progression or preparing for war.
1. Overview
In Last Z: Survival Shooter, the mastery tree lets you commit your hero specialisation toward one of two directions: Support or Combat. Each path unlocks a distinct set of boosts, and neither is universally better. Your choice should follow your goals: faster season progression and economy, or raw fighting power for Governor War (GW) and State vs State (SvS).
Switching trees is not free, so it pays to understand exactly what each side delivers before you commit. The sections below break down every benefit, then cover when and how to switch.
2. The Support Tree
The Support tree is built around economy, healing, and helping your alliance. It is the strongest choice for players who want to keep climbing without relying on combat.
Support Benefits
- Extra frostcore and icebloom output.
- Extra building boosts.
- Improved serious-to-slightly injured ratio, so more of your wounded troops survive lightly hurt.
- Extra 50% Alliance Help effect — one of the most powerful perks in the tree.
- Extra Virus Resistance.
- Extra Mastery EXP.
- A 1-hour Shield that can be used on other players.
- A Food or Wood Vault to protect resources from looting.
When Support Shines
This tree is excellent for faster Season 2 progression. Even if you cannot capture any higher-level tiles and feel stuck, you can keep growing your Influence Points — and the Support tree makes that grind noticeably easier. If you have not spent money on the season and want the most value from a free-to-play approach, Support is usually the better fit.
3. The Combat Tree
The Combat tree trades economy for overwhelming fighting power. It is the right call when your alliance is gearing up for war and wants to hit and survive harder than the opposition.
Combat Benefits
- Extra Attack and Defence boosts.
- Extra Damage boosts.
- Extra boosts specifically for SvS events.
- Extra troop capacity.
- Extra training speed.
- The ability to build an extra Season 2 combat building.
- Extra mortality stats — lose fewer of your own troops and kill more of the enemy's.
- An instant extra units ability.
- An anti-scout ability that hides your strength from enemy scouts.
When Combat Shines
This tree grants enormously powerful combat boosts. The effect compounds when the whole alliance switches at roughly the same time — a synchronised swap turns your alliance into a far more formidable force in both GW and SvS. If your group is committed to fighting, coordinate the move so everyone peaks together.

5. When and How to Switch
There is no fixed correct moment to switch trees, because switching costs resources. Plan around your season goals rather than reacting to a single event.
- Players with the Season Journey pass will already have received Mastery Passes, letting them switch for free.
- If you do not want to keep buying additional Mastery Passes, use the ones you have wisely — do not burn them on impulse swaps.
- If your alliance is planning a war push (for example, building toward the major mid-season conflicts around week 8 of the season), coordinate a group switch to Combat so the boosts land at the same time.
- Outside of those windows, many players find Support the better default, especially when progression and Influence Points matter more than fighting.
6. Summary
Choose Support for steady growth, economy, healing, and alliance utility — the path of least resistance toward higher Influence Points. Choose Combat when your alliance is ready to fight and wants synchronised, overwhelming power for GW and SvS. Because switching is not free, decide based on your real goals, spend Mastery Passes deliberately, and where possible move as a group so the benefits peak together.
